Features

The Arc’teryx Zeta AR uses 3-layer Gore-Tex and the C-Knit backer increases its softness and lightness, but this is less durable and feels hotter and clammier than Gore-Tex Pro. There are pit zips for temperature control, though. The weight of 442g is very appealing. You also get two large chest pockets. The hood only has rear adjustment though and the peak is not as stiff as others. 4/5

Fit

The men’s sizes are S-XXL and the women’s XS-XL. The jacket is about 8cm longer than some of the shorter designs so it easily covered my behind. The sleeves are also more profiled than others with a closer fit, yet the hem and cuffs didn’t ride up at all when I raised my arms during scrambles. The hood fits like a close-fitting beanie and moves effortlessly with the head. Hard to better. 5/5

Comfort

The low weight of 442g (size men’s L) and the use of soft 3-layer Gore-Tex with C-Knit backer mean the Arc’teryx Zeta AR is far lighter and more flexible and has a greater level of comfort when worn. Pit zips aid ventilation too. In foul weather the longer body length aids comfort but the peak does not provide much protection, as it is small. The soft fabric does not resist buckling in the wind as well as stiffer, heavier fabrics. 4/5

In use

In fine weather this is a great choice as it is so comfy, but in rough weather that batters the body it is less appealing as it does buckle under the wind. The two huge chest pockets are useful but having a dedicated pocket for maps or a GPS would be handy for some users. A hood with a bigger, more protective peak would also be a bonus in really bad weather. 4/5

Value

The price is high considering the features you get here, so while it is nice to wear in fine weather the price is less appealing. RRP: £360. 3/5

Verdict

The Arc’teryx Zeta AR’s fabric’s weight and softness are great, but in the worst weather other jackets have benefits. 4.0/5
